Hypersthene necklaces bring a quiet sophistication to silver jewelry. This iron magnesium silicate mineral displays a distinctive bronze-to-copper sheen across its dark gray surface, an optical effect called schiller. With a Mohs hardness of 5.5 to 6, hypersthene holds up well in pendant settings while maintaining its reflective character. Each stone forms in igneous and metamite rocks, with notable deposits in Canada, Norway, and parts of the United States. Our collection pairs this understated gem with .925 sterling silver.
